$2\mathrm{.}12$ LAB: Name format

Many documents use a specific format for a person's name. Write a program that reads a person's name in the following format:

firstName middleName lastName $($in one line$)$

and outputs the person's name in the following format:

lastName, firstInitial.middleInitial.

Ex: If the input is:

Pat Silly Doe

the output is:

Doe, P$.$S$.$

If the input has the following format:

firstName lastName $($in one line$)$

the output is:

lastName, firstInitial.

Ex: If the input is:

Julia Clark

the output is:

Clark, J$.$

def format$\_$name$($name$)$:

name$\_$parts $=$ name.split$()$

last$\_$name $=$ name$\_$parts$[-1]$

first$\_$initial $=$ name$\_$parts$[0][0]$

middle$\_$initial $=$ name$\_$parts$[1][0]$ if len$($name$\_$parts$)==3$ else $\text{'}\text{'}$

formatted$\_$name $=$ f$"\{$last$\_$name$\},\{$first$\_$initial.upper$()\}"$

if middle$\_$initial:

formatted$\_$name $+=$ f$".\{$middle$\_$initial.upper$()\}."$

return formatted$\_$name

# Read the name from the user

name$\_$input $=$ input$("$Enter the person's name: $")$

# Format and print the name

formatted$\_$name $=$ format$\_$name$($name$\_$input$)$

print$($formatted$\_$name$)$
